(54) Method and device for measuring bearing ring strain during mounting


(57) The invention refers to a method and a device for integrated cable signal adjustment, when mounting a bearing with a taper bore on a shaft, whereby the strain is measured at the bearing ring as the bearing ring is driven up axially on the shaft, and the instantaneous clearance, reduction in the bearing is calculated on basis of the measured strain, and using the reduction of the internal bearing clearance for determining the amount the bearing shall be driven along the shaft, that for compensating a systematic measurement error in form of a too high measurement result appearing when the strain measurement takes place on the side face of the bearing ring instead of on the inner envelope surface thereof, a compensating device (17) is connected in a cable (16) between a sensor (15) fitted to the point of measurement and an indicator displaying the measurement result, and that the compensating device (17) is caused to lower the measurement signal before reaching the indicator, with a factor corresponding to the measurement error.
